IMPROVEMENT IN REVERSIBLE BOOT-HEELS.

Specification forming part of Letters Patent NO. 116,758, dated July 4, 1871.

To all whom t may concern:

Beit known that we, FREDERICK RICHARDSON and FRANCIS HACKER, both ofthe city and county of Providence and State of Rhode Island, have invented certain new and usel'ul Improvements in Reversible Boot-Heels.

On the 5th day Of May, 1868, Letters Patent Of the United States were granted to FREDER- ICK RICHARDSON for a certain novel reversible boot-heel, and our present improvements relate thereto; and consist in providing the reversible section Or tap With frictional metallic surfaces flush with the Outer rim for the purpose of securing' a foothold in slippery places.

Referring tO the drawing, Figure l represents, in perspective, a boot with Our improved reversible heel attached. A represents the socket-plate, which is permanently attached to the boot-heel. This plate is in the form of a boot-heel, and is provided With an inward-projecting ange, l), at its upper edge, Which is perforated for screws, with which it is attached to the boot-heel. B represents the reversible heel-tap. Fig. 2 represents the socket-plate A detached. Fig. 3 represents the reversible heel-tap B detached. Fig. 4 represents the reversible heel-tap B provided with frictional surfaces. ein each case represents solid metallic spurs; f, cylindrical studs; and g, corrugations. The Wearingsurfaces Of these spurs, studs, and corrugations are Hush With the edge Of the outer rim.

Forlight boots thereversible heel-tap B (which consists of a double-recessed metallic tap with an outward-projecting iiange, (l) has its recesses filled with leather, rubber, Wood, or other desirable material. For Ordinary Winteruse on heavy boots the solid spurs e are employed. For miners boots the cylindrical studs for corrugations g are used in preference. These latter are also attached tO and form a part of the tap.

The intermediate spaces may be filled with any suitable composition or left open, as may be desired. If filled With any material softer than the metal used thi s intermediate matter will, ofcourse, Wear away faster than the metal, and so leave the spurs Or corrugations exposed, thereby securing a firm footing. As may be desired, the reversible tap may be Wholly provided either with the spurs, studs, or corrugations, or with any number of each in one. y

Having.;` thus described our improvements, We claim as new and desire to secure by Letters Pat ent- The reversible metallic heel-tap B, provided with the solid, cylindrical, or corrugated frictional surfaces e, f, and g, as and for the purposes specified.
